DOUCHE NozzLE.

Application filed May 14, 1919, Serial No. 297,062.

This invention relates to improvements in douche nozzles, such as areused chiefly in cleansing and irrigating, or in conveying liquidmedicaments to the internal parts of the vaginal cavity.

The interior structure of this cavity is such that iets, streams orsprays from ordinary nozzles act merely superficially, and, regardlessof the force used, fail to reach the interstices formed by the sinuousfolds or convolutions of the overlapping membranes which constitute itsenveloping walls.

lt is essential when irrigating this cavity that thc entire interiortract surfaces be'subjected to treatment, Apreferably in an easy, safeand convenient manner, without discomfort or pain, condition which, sofar as is known, has never been satisfactorily met.

Due to the peculiar construction and disposition of these flexible andpliable membranic walls they are readily dilated or distended andinstruments for such purposes are in use by surgeons, but so far as I amaware, no device is commercially known that may be freely used in safetyby the individual herself.

The principal object of this invention is to provide a douche nozzlewhich fulfills the foregoing conditions, effectually and painlesslyexpanding the vaginal cavity, loosening the folds of the membranes tosuch an extent that liquid supplied by the device is brought intointimate Contact with the surface, thoroughly flushing the same.

A further object is to provide a douche which can be safely used even byinexperienced persons, the operations of insertion and expansion beingof the most simple and elementary nature.

A further object of the invention is to provide a nozzle which willallow an easy and Continuous outflow of the water or other liquiddischarged through the nozzle so that the force of the discharge and theconsequent cleansing effect will not be impaired.

Still another object is to provide such nozzles in forms which may bethoroughly cleansed and rendered antiseptic, Vand which, due to t-hesimplicityv of construction, can be manufactured at moderate cost. Y

Figure l is a longitudinal sectional View talren substantially throughthe center of a douche provided with a nozzle, made in ac- Renewed March3, 1927. 1

cordance with the invention, the dilators being shown'in a. foldedposition; and

Fig. 2 is a` fragmentary side elevational view of the same, the dilatorsbeing shown extended. p y 1 Referring to the drawings, l indicates abase piece or nipple to which the rubber tube from the ordinary ,douchebag may be attached. This piece has a central bore for the passage ofthe water or other liquid and at its outer end this bore is somewhatenlarged and threaded to receive t-he correspondingly threaded end of aninner tube 2 whosebore forms a` continuation of the water passagethrough the piece l. The tube 2 is provided with an enlargement 3 at itsouter end,lhere shown as integral with the tube, the enlargement beingformed with aseries of pockets 4 for receiving dilators 5 when in theclosed position indicated in Fig. l. As shown, the

dilators are four in number and are symmetrically arranged around thecircumference of the tube, but a greater or less number may obviously beemployed if desired.

The dilators and pockets terminate somewhat short of the end of theenlargement 8, which is `formed of a perforated cap 6 through which thewater or other liquid is discharged, the tube walls between the pockets4 being also preferably perforated to distribute the liquid over theentire surface of the walls of the cavity to be irrigated or treated.The end cap 6 is made detachable to permit the ready insertion of asponge or gauze containing a medicated solution to bey sprayed on thesurface by the water from the tube 2.

rlhe dilators 5 are pivoted on a sliding collar or sleeve 7 supported onthe tube 2 immediately below the expanded portion 3 and the shoulderbetween the tube 2 and the expanded portion is shaped so as to act as acam to force the dilators out on their pivots into their expandedposition shown in Fig. 2 as the sleeve 7 is moved forward on the tube 2in Fig. l, that is, a bow-shape, their outer ends being turned inward tolie well within the pockets 4 when the dilators are contracted while themiddle convex portions of the dilators are substantially flush with thecircumferential wall of the enlargement so'as to present no projectingparts to engage and irritate the delicate surface of the cavity.

The mechanism for shifting the sleeve 7.

along the tube 2' to operate the' dilators may be et any suitabledesign, but I prefer to employ for the purpose a pair oi' arms or linlrs8 pivoted to the lower edge ot the sleeve T at diametrically oppositepoints, the links being' preferably extended through holes in av guidocollar 9 formed on the tube 2 at the point indicated7 and connected attheir lower ends to the 'forked end of a bell crank lever 10 pivoted ina block 11 attached to the tube 2 near its outer end. The forked end otthe bell cranlr embraces the tube 2 as shown, and its other end is'formed to provide a thumbpiece or handle 12 by means oit which the bellcranlc is operated, the arrangement beine` such that the sleeve 7 willbe raised or pushed outward when the thumb-piece is pressed toward thenipple 1.

ln order that the dilators may be remlily operated with one hand thesleeve T is pret erably shifted in the `reverse ilirection by springs 13which may be arranged, as shown7 on the links 8 between the collar 9 andthe fork ot the bell crank 10 to be compressed by the upward movement otthe liorle The block 11 is recessed 'to tit (wer a luf;` 14 on the tube2 to which it is attached by a screw, and pivot-ed .in a slot in thelower Y portion oiI the block is a latch 15 which projects through aslot in the bell cranl; 10 and has its lower edge notched to engage atooth formed at the end ot the slot in the bell crank whereby thedilators may be locked in open or partially open position and there.-

by relieve the user from holding' the thumbpiece against the pressure otthe springs. The latch may be held yieldingly in engagement with thetooth by a spring pin mounted in tle bell crank in the manner shown.

The operating mechanism for the dilators is covered or enclosed by anouter sheath or casing; 16 of the same external diameter as theenlargement between the pockets Ll. whereby when the dilators are closedthe instrument has a smooth tubular exterior surface. trom lend to end.

The sheath 16 is held in place by a short sheath or casino` section 17which is notched on one side to receive the blocli 1l with the. attachedbell crank 10 and latch 15. ln assembling' the device, ai'fter thesleeve T is placed on the tube 2 and the linlrs 8 mounted in the guide9, the sheath 16 will be slipped over the tube until its upper end abutsagainst the shoulder 18 formed at the base et the enlargement 8. Thesheath is notched indicated at 1,9 at points coinciding` with thepockets l vto permit the projection ot the dilators .in the mannershown. The bell crank 10 will then be a '-taclied to the lower ends ofthe links 8 and the block 11 seated on the lug 14t and fastened inplace. rllhe short sheathor casing sect-ion 17 will then be slipped overthe end ot the tube? into engagement with the lower end ot the sheath;

nfs-eases profession. The dilators are arranged to lic substantiallywithin their cavities and the connections between the external opera i Amen'iber and the dilators are entirely within the outer periph-ery oi"the nozzle so that at the entrance there is nothing); to irritate orcause reflex contraction ot the sphincter muscle, which not onlyinjurious but interl'eres with the outtlow ol thev liquid. Also the,shape ot the dilators such as to present a smooth and rounded surtace otmore or less extended area tor contact with the walls ot the cavity toavoid all dancer et injury.

It is also to be understood that while the nozzles are designedparticularly ttor vae.'- inal douches. they may obviously be used `l'orother purposes, and the invention is not limited to such special use.
